TUBE-REPAIRING CLAMP.

Application filed July 7,

My invention relates to improvements in pneumatic tire repairing devices and has reference particularly to an arrangement for deflating the portion of the tire to be mended and for holding and clamping the' same during the application of the tire patch.

In order to mend an inner tube which has become punctured it is ordinarily necessary to remove all of the air from same. The task of doing so is not always an easy one and includes entire removal of the tube from the shoe. 1 have overcome the necessity not only of removing the tube from the shoe in order to mend the same, but of deflating the entire tube so that a atch ma 7 be a plied.

The object then of this invention is to provide an apparatus which will hold the tube at the place to be patched and at the same time remove all of the air therefrom. I accoinplish this objectby means of the device illustratively exemplified in the accompanying drawings, in which:

Figure 1 is a perspective view of the invention showing the parts separated.

Figure 2 is a transverse sectional view of the same in the act of deflating the tire; and

Figure 3 is a substantially longitudinal sectional view of the invention showing a modified form of clamping means.

Referring to the drawings, denotes a base boa'rd preferably square in plan and provided adjacent its four corners with upstanding threaded pins 11 projecting from what will be referred to hereinafter as the working face of the base board or bed 10. The two pins 11 at the rear edge of the bed 10 carry washers 12 and thumb screws 13 while the two pins 11 at the front of the bed project through the latter and extend substantially an inch or more beyond the un der face for the purpose of holding the front edge of the bed away from a wall when the device is hung up by means of an eye 14 during the mending operation, the eye 14; being attached to the rear edge of the bed.

Figure 1 illustrates the bed 10 with a portion of a tube 15 in place ready to be patched. the tube being placed between the front and back pins 11, and held by means of a U- shaped frame 16. The closed end of the frame 16 is inserted beneath the washers 12 and the front free ends are provided With 'bar 21 substituted therefor.

1927. Serial No. 204,127.

holes 17, which when the frame is brought down over the tube 15, receive the front pins 11 and enable the thumb screws 18 to be tightened. To deflate the tube a sliding plate or board 19 is arranged beneath the frame 16 and seated against a shoulder 20 cut in the under inside surface of the arms of the U-shaped frame. After the frame 16 has been clamped in position with the board 19 over the tube 15, the board is removed by sliding it out of the frame, thereby leaving the punctured portion of the tube exposed, completely deflated and ready to have the patch applied.

In the embodiment shown in Figure 3, the front pins 11 are omitted and a U-shaped The arms of this bar are provided with openings 22 which when the arms are inserted through the openings 17 and those used for the pins 11, enable pins 23 to be inserted beneath the bed 10. The cross piece of the bar 21 is pressed against the frame 16 until the tube has been deflated and firmly held, after which opera tion the pins 23 are inserted to hold the bar in clamped position. The ends of the bar 21 suffice to hold the device away from the wall or surface upon which the device is hung until the patch is dry.

The operation of mending a tube by the aid of my invention is extremely simple. The bed 10 is freed of the frame 16 and the tube 15 arranged as shown in Figure 1. The frame 16 is then placed in position and the nuts 18 tightened. The tube should then be free from air and the board 19 is removed to expose the portion of the tube to be mended. After the patch is applied the device is hung up until the patch has set.

What I claim and desire to secure by Letters Patent is:

1. In combination, means to receive a portion of a tube to be patched, means to clamp the same against the first means and having a portion removable to expose the tube within the second means.

2. A tire holder to aid in the repair of inner tubes, comprising a bed board having a working face to receive the portion of the tube to be mended, a U-shaped frame to be clamped over the bed and against the tube, means carried by the bed to clamp the frame,

and a deflating board slidably carried by the frame to press the tube and to be removed to expose the tube between the portions of the frame.

3. A tire holder, as claimed in claim 2, in which the bed is provided with projections extending from the back thereof to hold the front of the bed away from a support, and means at the back end of the bed to carry the device in hanging position. 10

In testimony whereof he has afiixed his signature.
